LOO M SPECIFICATION forming part of Letters Patent No; 636,773, dated November 14, 1899.

Application filed February 27, 1899. Serial No. 706,943. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM C. EDLER andFRANK WINDLE, citizens of the United States, residing atthe city of Philadelphia, in the county of Philadelphia and State of Penn-' sylvania, have invented certain new and useful Improvements in Looms, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of ourinvention is to .provide a simple and efficient electromagneticpicker,

mechanism for looms with the view of dispensing with the usual picker-sticks and their many eoacting parts.

To this end the invention comprises various features of construction and arrangement of parts, which will be hereinafter set out in detail and be duly claimed.

In the drawings, Figure 1 is a vertical sec-- tion through a portion. of a loom embodying our invention in one form thereof. Fig. 2 is a front view of the lay and adjuncts. Fig. 3 is a horizontal section on the line 33 of Fig. 2. Fig. 4 is a diagramof the electrical connections. Fig. 5is a detail of one of the switchlevers, showing the shuttle-clamping arms in section. Fig. 6 is an elevation of one of the shuttles which we prefer to use.

A is the framework of the loom; B, the

main shaft; B, a counter-shaft geared therewith and provided with-a crank b; C, the lay, connected with said crank by a pitman b; C, the shuttle-race on said lay; D, the vertically-movable shuttle-boxes at the respective ends of the lay, and E one of the shut- These parts are of usual and wellknown construction, excepting as hereinafter described. The shuttle is the same as heretofore, excepting that, a greater quantity of metal is used in its construction-that is, the ends 6 and bottom e of the shuttle are constructed wholly of magnetic metal let into the wooden body 6*. If desired, however, the entire shutt-le may be of metal.

Suitably disposed on the lay adjacent to the respective shuttle-boxes are two clcctromagnets, preferably solenoids, I", through which the shuttle is designed to travel in its passage from side to side of the loom. The solenoids are supported by bracket-sf, ol non- .ployed there will conducting material, and are energized'from a suitable source of electricity, provision being had whereby the respective circuits therefor are made and broken at predetermined intervals in respect to the actions of the lay. Hence if a shuttle be contained inoue of the boxes in the horizontal plane of .the shed and the adjacent solenoid tle will be attracted into and through the solenoid. If just before the shuttle has been fully attracted by the solenoid. the current to the latter he suddenly cut ofi, themomentum attained by the shuttle in entering the solenoid will be sulficient to project theshuttle bodily across the lay and into the oppositeshuttlebox. Thereupon .if the circuit connected with the other solenoid be correspondingly made and broken the shuttle will be again thrown across the loom. In this way by making and reaking the respective circuits in alternate succession the shuttles will be shot from side to side of the loom, pick and pick.

In the particular construction herein illustrated electrical connections are provided whereby when a be no liability of the solenoids being energized in the event of shuttles being'accident-ally contained at the same time in corresponding boxes at the respec tive sides of the loom. Such connections are as follows: 0n each of the brackets f is a switch G, comprising two contact-points g g and a lever g one arm of which latter is extended forwardly of the adjacent shuttle-box and adapted to be actuated by the usual spring-controlled clamping-armed in a manner to eltect the shifting of the lever from one point to the other at stated times. nose of the forward arm of the lever is beveled, as at so, to facilitate the vertical movement of the opposing clamping-arms d. Normally the switch-levers are maintained upon the contact points 9 through the action of suitably-disposed springs g. The solenoids are electrically connected with the adjacent contact-points g by means of con ductors hand with the distant contact-points g by means of conductors 7L. One of the switch-levers is connected with the source of electricity II by a conductor 6, the other he energized the shut-- The series of shuttles are emthe lay to be forward. In that case the clampthe operation just described repeated.

'duced rearward end thereof permits the conswitch-lever being connected by a conductor i h with a stationary contact-piece 71 which is disposed on a cross-bar of the main frame in the path of a contact-plate 7L5, preferably yielding, on the back of the lay. The latter plate is connected with the source of electricity by a conductor h.

The operation isas follows: Assume the upper compartment of the left-hand shuttle-box to contain a shuttle, the corresponding compartment of the other box to be vacant, and

ing-arm for said shuttle being pressed outward bears against the adjacent switch-lever cuit and adapted to be moved into and outof contact by the action of the lay.

2. In a loom, the combination with the lay provided with a shuttle-race, and the shuttle, of a solenoid adjacent to one end of said race and in the path of the shuttle, an electric circuit for said solenoid, and contact devices connected with said circuit and adapted to be moved into and out of contact by the action of the lay.

' 3. In a loom, the combination with the lay provided with a shuttle-race, and the shuttle, of eleetromagnets adjacent to the respective ends of said race, electric circuits for said magnets, and contact devices connected with g and connects the latter with the point g, the electric circuit only being interruptedbetween the two contact plates 7% h. The i clamping-arm for the upper compartment of the right-hand box being retracted does not affect the normal position of the switch-lever adjacent thereto, and hence the circuit for the right-hand solenoid is broken at the two switches and also betweenthe plates 7L4 h Now it will be seen that during the backward stroke of the lay the plate thereon will make contact with the stationary plate, and thereby complete the electrical circuit of theleft-hand solenoid, which latter, being energized, will attract the shuttle. Just before the shuttle has been fully retracted the tapered or retiguous clamping-arm to swing inward, and in consequence the coacting switch lever moves to its normal position, thereby breaking the circuit, whereupon the shuttle in virtue of its momentum is shot through the shed and into the oppositeshuttle-box. The clauipbar on the latt r is pressed outward by the shuttle, as usual, thus shifting the right-hand switch-lever on to the contact-point 9. Before the connection has been made, however, the lay is moved forward to break the contact between lhc two plates 71 h. In the next following bar S'iltlib} ot' the laythe circuit of the right-hand solenoid is completed and It will be obvious that as the shuttle-boxes are raised and lowered in the usual manner by the box-motion the predetermined shutsaid circuits and adapted to be moved into and out of contact by the action of the lay.

4. In a loom, the combination with the lay, its race, and the shuttle, of solenoids adjacent to the respective ends of said race and in the path of the shuttle, electric circuits for said solenoids, and contact devices connected with said circuits and adapted to be moved into and out of contact by the action of the lay.

5. In a loom, the combination with the lay, the shuttle-boxes, including clamp-arms, and the shuttle, of electromagnets adjacent to said boxes, electric circuits therefor, switches in said circuitsadjacent to the clamp-arms of the respective boxes, and adapted to be operated by said arms, as described, and contact devices connected with said circuits adapted to be moved into and out ofcontact by the action of the lay.

the shuttle-boxes including clamp-arms, and the shuttle, of solenoids supported adjacent to the respective boxes and in the path of the shuttle, electric circuits forsaid solenoids, switches in said cin nits adjacent to the clamp-arms of the espectivo boxes, and adapted to be operated by said arms, as desaid circuits and adapted to be moved into and out of contact by the act-ion ol' the lay.

i 7 In a loom, the combination with the lay, it? shuttle-boxes, and the shuttle, of solenii s supported adjacent the respective boxes tles and the clamping-bars therefor will act l'and in the path of the shuttle, electric cirupon and be actuated by the electrical con nections in the manner above explained. It will also be obvious hat in the event of shuttles being accidental i supported adjacent to 1 the respective solenoi-ls both circuits willbe cut olt through the act on of the switches and i that, therefore, there ill be no liability of two shuttles being sinr ltaneonsly shot from i opposite sides of the l0( in into the shed.

We claim as our invention-- 1. In a loom, the :ombination with the lay provided with a shuttle-race, and the shuttle, i of an electromagnet adjacent to one end of said race, an electric circuit [or said magnet, and contact devices connected with said circuits [or said solenoids, switches in said circuits for the respective solenoids, means whereby said switches a reopened and closed at predetermined intervals, and contact de- "iees connected with said circuits and adapted to be moved into and out of contact by the action of the lay.

In testimony whereof \ve allix our signatures in presence of two witnesses.
